Abstract
A method for optically transmitting data between a transmitter and a receiver is disclosed, in which a color coding method based on a plurality of elemental colors is provided for the coding and transmission of the data, which color coding method involves a respective elemental color being sent by a respective transmitter-end optical radiation source and being received at the receiver end by a respective optical radiation receiver. The method provides for a control loop to be formed between the transmitter and the receiver, wherein the transmitter sends calibration messages to the receiver, and wherein a piece of compensation information is ascertained by comparing at least one channel property of at least one received calibration message with a corresponding channel property of at least one previously sent calibration message, and wherein the transmitter takes the compensation information as a basis for adjusting at least one transmission parameter.
